They look more like floating hot air balloons than living things, but jellyfish will let you know quickly that they’re alive. Those colorful, bell-shaped tops have snakelike tentacles that sting!

About 95% of a jellyfish is made up of water. That’s why they seem to melt away on the beach.

Most of the body parts are for eating. They don’t have bones, eyes, or even a brain!

But don’t let that fool you. God gave these floating feeders complex designs to push through the water by jet propulsion and grab a meal with their four frilly arms.
